DURAPOSIT™ SMT 820 is a high phosphorous Electroless Nickel specifically formulated for use in combination with the AUROLECTROLESS™ SMT 520 Immersion Gold process. The phosphorous content of the electroless nickel deposit improves the corrosion resistance of the ENIG deposit, particularly for selective gold processes using OSP coatings in conjunction with ENIG, and is suitable for products that require enhanced corrosion resistance such as mobile devices, automotive, and medical applications.

Key Features of the process:

Excellent corrosion resistance from a high P electroless nickel process with P content of 10.5-11.5%
